Implication

Behavioral study demonstrates that notched stimulus training selectively aids occluded object recognition in pigeons, indicating visual experience improves two-dimensional scene decomposition.

Key Points

To determine whether training pigeons with partially erased or notched stimuli improves recognition of partially occluded objects and whether any enhancement generalizes to novel stimuli.
Trained pigeons on visual discrimination using either partially erased stimuli or notched stimuli containing a thin boundary gap between an object and a surface.
Tested pigeons' subsequent recognition accuracy on familiar objects under partial occlusion as well as on novel occluded objects.
Erased stimulus training produced no detectable improvement in pigeons' recognition of partially occluded objects.
Notched stimulus training significantly improved recognition performance for familiar objects when partially occluded, but this benefit failed to transfer to novel occluded objects.
